Vacuum Tubes
The first electronic amplification of sound was done with Vacuum Tubes. We have pre-amp, power and rectifier vacuum tubes among other types in New Old Stock from the golden era of American & European manufacturing as well as current production tubes from today.
The JJ Electronic 2A3 features a robust construction in a beautiful thick glass envelope. The JJ 2A3 offers 40 Watts of plate dissipation which far surpasses the headroom of other 2A3 tubes by 25 Watts. The single plate build and increased ratings give this tube the highest reliability. The JJ 2A3 has amazing detail and clarity with excellent separation.
